Science Daily  September 14, 2021 The reactions in DNA-based combinational logic computing are mostly achieved through a manual process. For DNA-based Boolean logic, researchers in South Korea have fabricated a DNA-based microfluidic processing unit (MPU). They cast polydimethylsiloxane using double-sided molding techniques for alignment between the microfluidics and valve switch. For a uniform surface, molds fabricated using a three-dimensional printer were spin-coated by a polymer. For programming control, the valve switch arms were operated by servo motors. In the MPU controlled via a personal computer or smartphone application, the molecules with two input DNAs and a logic template DNA were […]
